Abstract

Abstract

Recurrent emergence of public health emergencies has unveiled systemic deficiencies in urban safety risk management within aging residential neighbourhoods of megacities. Anchored in the theoretical triad of “risk source， risk exposure， and mitigation capacity” for urban safety resilience， this study employed Beijing megacity as a representative case to systematically delineate risk frameworks and resilience-enhancing transformation pathways for such neighbourhoods under sudden public health crises. Initially， the analysis initiated by dissecting the cascading risk propagation mechanisms of public health emergencies and characteristics of public health emergencies through the lens of “risk source”. Subsequently， it diagnosed multidimensional vulnerabilities embedded in population groups， social dimensions， economic aspects， resource， and environmental elements of these neighbourhoods， framed as “risk exposure”. Ultimately， it formulated targeted strategies and pathways for resilience transformation within the “mitigation capacity” framework， thereby crystallizing an integrated urban safety governance cycle （risk source containment → risk exposure optimization → mitigation capacity intervention）. This aims to provide theoretical support and practical guidance for grassroots safety capacity building and urban renewal in megacities.
